The code seems to first check the validity of the read handle associated to the
ComTime object but then proceeds to dereference it even if it's not valid causing
WARNINGs. It sounds like this information is only valid in Cosmics data, so its absence is not unexpected. I demoted the
INFO message to
DEBUG and dereference the handle iff it's valid. While at it I dropped the, now defunct,
atlas_depends_on_subdirs in the CMake configuration.
